To all whom-it may concern: i

Be it known that I, EDWARD J. WINsLow, a citizen. of the United States,residing at Chicago, in the county of Cook and State of lllinols, haveinventedcertain neWand useful Improvements inFireproof Roofing-Tiles, ofwhich the following is` a-specification.

This invention relates to'im rovements in reproof roofing tiles, and itas for its salient objects to provide a construction which combinesgreat strength `and rigidity with lightness and an eIicient form; toprovide a construction ini'which the rigidity of the tile against'bending stresses is reinforced by transverse and intersecting"lstrengthening ribs formed upon the under side ofthe tile only and therigidity and strength of the tile is further increased b extendingreinforcing wires throu h said' ribs; 4to Iprovide a construction w 'chis es ecially effective in its lities, the exterior form of theti ebeing such that the rain cannot beat in or be driven inwardly past thejoints by wind; to provide in conjunction with the main tile members calike batten members which effectively over e and close the jointsbetween the meetin edges of the maintile members; to provi e aconstruction which acter referre is adapted to be readily and reliablysecured to a roof byl means of channel members, Z-y

bars or other commercial shapes of struc,-

tural iron; and in general to roduce an eili-I cient and improvedconstruction of the charuto.

To the above ends the inventionconsists 1n the matters hereinafterdescribed and more artlcularly pointed out in the` ap- The inventionwilll be readily understood from .the following description, referencebemigi llijadto the accompanying drawings, in w c .Figure 1 is aperspective View of afragmentary portion of a roof covered with tilesembod ing a referred form of the invention; parts eing' roken out .andother parts shown in transverse section; Fig. 2 is a perspective view ofthe under side of one of the main tile members, parts being broken outto reduce the le th of the /i ure; Fig. 3 is a transverse sectional viewt ough a portion of a roof frame andthe tiling thereon,

showing particularly' the manner in which vtile members interlock with4the supporting irons and the manner in which the cap or batten membersoverlap the main tile members; Fig. 4 is a fragmentary detail showin themanner in'which the tiles are applied an fit against the base portionlof' a turret or other Fperpendicular wall rising from l the roof; 5 isan end elevation of one of the tiles. yi 6is a fra mentary sectionaldetail taken vertically and longitudinally throu h .the assembledstructure in the plane of t e joint'shown at the left end of Fig. 5.

Describing first in detail the form-and construction of one of the maintile members, 1

designates as a whole one of such members .of the intersectingstrengthening ribs hereinbeforedescribed, the main body of the tile isof practically uniform thickness, as indicated clearly in Fig. 5.Extending along its upper margin at the under side thereof 1s a hookesha ed flange 10 adapted to engage over and hoo upon the edge of achannel member or Z-bar,.,as indicated at 11 and 12. Extending along itslower edge at its under side is a downturned ilange 13" adapted to hookIover the upstanding flange 8 of the tile belonging to the'nextlowertier, as best seen in section of Fi 3. The end margins of the main tilemem ers are ordinarily perpendicular to the main plane ofthe tile, asbest seen in Fig. 3, bt lin case the up er end of the Ntile is formed toabut andp t against a vertical wa1l,as for example the base of a turretskyflight, as indicated in detail Fi 4,-.then the correspondin ustanding an downturned anges- 8 an `10 will be inclined to the mam planeof the tile so as to abut againstv the vertical frame .structure. i

The longitudinally extending intermediate Vribs 6 are desirably formedby omitting the corrugating grooves of. the under side oppoi .sitecertain ones of the lridgesrof the upper side, thus forming barsapproximately diamond-shaped in cross section but with the lower angleof each bar omitted and a flat face 6 thus formed. The lower sides ofthese bars 6 extend substantially below the apices 14 of thecorrugations of the under surface. form halves of the intermediate ribs;the tile being so formed that its lateral edges are coincident with theapices of the outermost ones of the upper corrugations or ribs. Thetransverse strengthening ribs are of the same thickness as thelongitudinal ribs, lie in the same plane with the latter and are incross section desirably rectangular, as seen clearly in the perspectiveFig. 2. Reinforcingwires are arranged to extend both lon- 'tudinally andtransversely through the body of the tile'for the purpose of addinggreaterc rigidity and strength to the structure. Describing them, 15designates transverse wires, of which there are two arranged toextendjthrough each transverse intermediate rib 5 and one through eachof theend ribs 4 these wires being located as near the lower outersurface of the respective ribs as prac'- ','ticable without exposing thewires, in order that they may have a truss effect to resist bendingstresses brought upon the tile. In the same general way other wires 16are extended longitudinally through the intermediate and marginallongitudinal ribs 6. It will be understood that both the transverse andlongitudinal wires extend the full length and width, respectively, ofthe tile member; these wires being embedded during the formation of thetile.

As a further feature of the invention, I provide caps of peculiar shapeand construction for overlying and closing the' joints between themeeting edges of adjacent tiles. These caps are designated as a whole 17and each cap is of a length e ual to the length of the tier of tiles towhic it is ap lied. In cross sectional form the main bo y of each cap isthat of an inverted V-shaped trough,

the an le of inclination and dimensions 'of the inc 'ned sides'of whichconform to and fit upon the corrugation formed by the two meeting edgesof the adjacent tiles, as shown clearly in Fig. 5. At its upper end,each cap is provided with an upstanding liang'e 18 which, when the capis in position, abuts and fits against the sides of the upstandingflanges 8 of the tile members, as seen in Fig.

. 1. At its lower end each cap is provided withiV a downwardly extendingflange 19 which hools over theu standing flange 18 of the next lower caof t e series. The lower edge margin 20 o the downturned flange 19 ofthecap is of-inverted V-shape to lit accurately upon the downwardlydivergent upper surface of the next'lowercap. `Preferably thelateralmargins 21 of the cap members 17 extend to the bottoms 'of thecorru- The marginal lateral ribs 6 are in gating grooves of the tilemembers and fit against the opposed inclined surfaces, as seen clearlyin Fig. 5.

With the title and cap members constructed and arranged as described, itwill be obvious that the roof surface thus formed presents no recessesor angles in which water, snow or ice may become permanently lodgedsince the surfaces all pitch downwardly and form unobstructedwater-sheds. Moreover it will be seen that the joints are so overlappedthat rain or water cannot be driven through the joints beneaththe titlesin such manner as to penetrate the roof. The overlapped and interflangedarrangement of the tiles and caps is .of particular importance in makingthe roof weatherproof against rain accompanied by violent wind. Theconstruction of the tile as a whole is extremely simple and light, andof a form which readily lends itself to molding in a rapid andeconomical manner.

While the construction described constitutes a preferred embodiment ofthe invention, it is nevertheless to be understood that the details maybe modified to some extent without departing from the spirit of theinvention.

I claim as my invention:

1. A roofing tile formed from plastic material, having a main bodymember relatively thin and longitudinally corrugated as to both itsupper and lower sides, an upstanding flange extending across its uppermargin, a downturned flange extending across its upper end margin, adownturned flange extending across its lower end margin, and a pluralityof reinforcing ribs extending across the main body at the lower sidethereof one or more of which extends across the central part of thetile.

2. A roofing tile formed from plastic material, having a main body ofenerally rectangular form and longitudinal y corrugated both as to itsupper and lower sides, marginal strengthening ribs extending along eachof the four sides of the tile, longitudinal ribs eX tending the lengthof the tile between the lateral margins l thereof, upstanding anddownturned flanges extending across its upper margin, a downturnedflange extending across its lower end margin, and reinforcing wiresextending through the body ofthe tile.

3. A roofing tile formed from plastic material, having a main body ofenerally rectangular form and longitudinal y corrugated both as to itsupper and lower sides, integral marginal strengthening ribs extendingalong each of the four sides of the tile, intermediate longitudinallyextending strengthening ribs, intermediate transverseribs, upstandingand downturned flanges extending along the upper margins of the tile, adownturned flange extending across its Plower end margin, and reinforcmgwires extending longitudinally cap member having its under side recessedand constructed to fit upon and overlap'the meeting edges of said tiles,said cap member being provided with an upstandmg flange across its upperend and a downturned flange across its lower end, and beingof a len thslightly in excess of the length of the ties,

substantially as described.

5. In' combination two tiers of rofing tiles, each tier comprising corruated tile members arranged edge to edge, t e lateral edges of said tilesmeeting in a line extending coincident with the apex of a corru ation,and cap members arranged to over ie the meeting edges of the laterallycontiguous tiles, 'each cap member being longitudinally groovedorrecessed in its under side to t u on the meeting edges of the tiles, andprovided at its upper end with an upstanding ange and at its. lower endwith a downturned ange, the ca member of one tier of tiles being of alengt to extend slightly below the lower edges of the tiles it overliesand the upper flange of the next lower cap member being hooked beneathand interengaged with the de ending flange of the upper cap member, sustantially as described.
